Unstuffed pepper casserole is a deliciously deconstructed low carb, gluten-free version of stuffed peppers. This casserole is made lighter by substituting riced cauliflower and lean ground turkey for the rice and ground beef that is more commonly used when making stuffed peppers.
As written, this easy healthy casserole makes 4 generous servings, but can easily be doubled when serving a crowd.

Recipe Notes
I used my favorite red bell peppers when making this casserole, but feel free to substitute with green, orange or yellow bell peppers, or a combination.
Rinse the frozen cauliflower under warm water and drained thoroughly in a colander (affiliate link) or strainer (affiliate link). If you used unthawed and undrained frozen rice cauliflower, your casserole will probably turn out a little watery.
